Problems solved by technology
The hydrogen circulation test system proposed in the Chinese invention patent CN200810060100.8 solves the problem of hydrogen recycling, but does not consider the energy consumption problem in the process of system operation. It adopts a single-stage gas supply in the design of the filling system. Compressor pressurization is completely adopted in the design of the recovery system, resulting in the waste of high-pressure energy and the improvement of pre-cooling energy
At the same time, the output pressure and displacement of the gas compressor in the patented system are very high, which increases the purchase cost of the compressor

Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings.
[0029] As shown in the drawings, the system described in the present invention includes three subsystems, one is the filling subsystem, which is different from the low-pressure gas source storage tank 9, the medium-pressure gas source storage tank 8, and the high-pressure gas source storage tank 7. The gas source storage tank of the pressure level, and the boost control device 18, the pre-cooling device 19, and the pneumatic booster 1 are connected through a high-pressure pipeline and a valve; Filling valve 30, discharge valve 31, low-pressure recovery buffer container 29, gas compressor 28, etc. are composed of pipelines; the other is an automatic control subsystem, which obtains relevant data such as pressure, temperature, and gas concentration from various sensors through an industrial computer 33 , to control the automatic operation of automatic valves or equipment...

The invention relates to a high-pressure gas storage container test system, and aims to provide a low-energy-consumption multi-stage self-pressurization high-pressure container gas circulating test system. The system comprises an injection subsystem, a pressure release recycling subsystem and an automatic control subsystem, wherein the injection subsystem comprises a pneumatic pressurizer, a pressurization control device, a precooling device and two or more gas source storage tanks with different pressure stages; the pressure release recycling subsystem comprises a flow control device, a low-pressure recycling buffering container and a gas compressor; the automatic control subsystem comprises an industrial control computer, an automatic valve and a sensor; the industrial control computer is connected with the automatic valve, the sensor, the pressurization control device, the precooling device, the gas compressor and the pneumatic pressurizer respectively. According to the low-energy-consumption multi-stage self-pressurization high-pressure container gas circulating test system, the use amount of hydrogen and the compression energy consumption of hydrogen are reduced, and the energy consumption of the precooling device is reduced. According to the system, high-pressure gas in a container to be tested is completely used for pressurizing a medium-pressure gas source storage tank and a low-pressure gas source storage tank, so that supplementation of external energy is avoided, and energy is saved.
Description
technical field [0001] The invention belongs to the field of new energy, and relates to a gas circulation test system of a high-pressure gas storage container, and is particularly suitable for the gas circulation test of a composite material container to be tested with fuel gas (natural gas, hydrogen, etc.) as storage objects. Background technique [0002] With the increasing shortage of fossil energy and environmental pollution, gaseous energy sources such as natural gas and hydrogen with high energy efficiency and low emissions are playing an increasingly important role in current and future life. The containers used to store these gases are in order to obtain For higher volume storage density and mass storage density, carbon fiber composite containers with high storage pressure (20-70MPa), high strength and light weight are generally used. [0003] During the use of high-pressure vessels, the pressure fluctuations cause the fatigue of the vessel. At the same time, due to ...
